VE-LO CIPEDE.

SPECIFICATION forming part of Letters Patent No. 410,179, dated September 3, 1889.

Application filed April 4, 1889. Serial No. 306,044. (No model.)

To all whom it may concern.-

Be it known that I, Orro NEUHAUsER, of

Pforzheim, Baden, Germany, have invented an Improvement in Velocipedes, of which the following is a specification.

This invention relates to improvements in velocipedes, and has reference more especially to means for propelling the same.

In the drawings, Figure 1 shows a side View of my improved Velocipedes; Fig. 2, a rear View of the same; Fig. 3, a top plan View, partly in section; Fig. 4, a side elevation of the driving mechanism; and Figs. 5 to 8 show various details of construction.

Referring now to the drawings, a a represent the driving-levers, the latter of which is provided with ratchet-teeth c 011 its extremity. The lever a is rigidly secured to an arm a, which is also provided with ratchet-teeth a adapted to mesh with those of lever 0. Suitable bearings are provided for the lever a and cby forkingthe lower extremity of the brace 19. The upper end of the fork a is made with a slot a which is provided with a reciprocating block 01, said block being pivotally connected by the pin cl with the driving-chain f. This chain is supported by sprocket-wheels e e, through the former of which motion is imparted to the rear or driving wheel A. Through the downward motion of lever 01. the lever a will be caused to rise and the arm a will take a forward motion, carrying with it block (Z and consequently chain f. Upon the block at passing'beyond a point where the chain is tangential to both 6 and c it will take adownward motion, and when reaching a point in a line drawn through the centers of the wheels 6 e the lever 0 will begin to act,

and will continue to act until it reaches a similar point in the line drawn through e e in the rear of wheel 6'. When it reaches this point, the lever awill again be in position fora downward stroke, and such movement would cause the chain to travel forward, thus insuring a continuous motion of the chain in one direction. t

To provide for equal leverage upon the levers a c, in consequence of the block being in the lower part of the slot during the downward stroke of lever c, said lever is made shorter than lever a.

Having thus described my in ven tion,what I claim is 1. In a velocipede, the combination of the driving-axle with the sprocket-wheel c rigidly secured thereto, the second sprocket-wheel e, driving-levers a c, and the backward and forward swinging arm a, substantially as described.

2. In a velocipede, the combination of the lever a with the reciprocating block cl and chain f, which travels over the sprocket-wheels e e, substantially as described.

3. In a velocipede, the combination of the driving-axle with the sprocket-Wheel e rigidly secured thereto, with the chain f, sprocketwheel e, arm a, with reciprocating block d, driving-levers a c, and ratchet-teeth cand 03, substantially as described, and for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses,

OTTO NEUIIAUSER.
